CHANNING M. BOLTON, OF WASHINGTON, DISTRICT OF COLUMBIA.

BULLETIN OR INDICATOR FOR TRAINS.

SPECIFICATION forming part of Letters Patent No. 426,428, dated April29, 1890.

Application filed December 17, 1889. Serial No. 334,137. (No model.)

To all whom it may concern:

Be it known that I, OHANNING M. BOLTON, a citizen of the United States,residing at \Vashington, in the District of Columbia, have invented anew and useful Improvement in Bulletins or Indicators for Trains, ofwhich the following is a specification.

My invention consists of a bulletin-board adapted to be affixed to thewall of a stationhouse or in any other suitable locality, and havingadjustable devices to indicate the number of the train, whether it is ontime or not, and the hour of its expected arrival.

In the accompanying drawings, which illustrate my invention, Figure 1 isa front view of a bulletin-board; Fig. 2, a cross-section of the same.Fig. 3 isa view of the traiirnumber dial, and Figs. 4, 5, and 6 views ofthe reversible slat.

A is the bulletin-hoard, having an aperture B.

O is a revolving dial pivoted to the rear of the board and bearing onits face the proper train-numbers, which are displayed through theaperture on rotating the dial, and form in connection with thedescriptive matter permanently marked 011 the board a sufficientdesignation of the train.

D is a thumb-screw fitted to the axis of dial O, by means of which it isset.

E is a bracket or shelf projecting from the board and having the groovedsides 6 e, into which slip the reversible strip or slat F, having 011one side the words On time and on the other Late.

G is a time-dial, having adjustable hour and minute hands for thepurpose of indicating the hour at which the train is to be expected, theword Expected being affixed to the board in a proper relation to thedial to indicate its object.

The operation is as follows: The dial O is revolved to indicate throughthe aperture B the proper number of the expected train. The strip F isthen put in place, with one or the other side exposed, as the case maybe, and the hour and minute hands of the dial are set by hand to thetime at which the train is expected. I

In place of a revolving dial to indicate the train-number, I may, ifdesired, use a revolving drum, with the necessary figures placed on itsperiphery, as indicated in dotted lines in Fig. 2.

I thus provide a device of great simplicity, the train-number giving atonce all necessary information by reference to the schedule time of thehour at which the train is due, While the only uncertain element arisingfrom the delay of the train is plainly indicated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A railway-bulletin consisting of the board A, having the unchangingpartial description of a train, the aperture B, the revoluble dial 0,bearing the train-number, fitted in said aperture and forming with thepreceding a complete description of the train, the bracket E, adapted toreceive a reversible slat F, having on one side the words On time and onthe other the word Late, and the time-dial G, having upon its face theword Expected, and the adjustable hour and minute hands, whereby thecondition of the train is indicated, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
